I use this on my ulns 90 gallon aquarium in a BRS dual reactor and it works well for me. I also run bio pellets and I use this product to help keep my phosphates low when my pellets can't. I have a valve on my reactor so I can fine tune how much PO4 the GFO is removing.

I've been using GFO from BRS for awhile and have no complaints. Keeps phosphates in check very effectively. I always recommend GFO to anyone having phosphate issues.

Use it on all my tanksBy Williamon 7/22/2013

I absolutely can't do without the BRS bulk GFO. It drastically improved the water quality of all of my aquariums. A 180gal reef tank and a 110gal fish only. Phosphate levels are almost not existent now after using the GFO, especially in the dual GFO and carbon media reactor.
